Build a week around this activity
A week gives you what to gather, one change at home and one thing to observe. It starts with four short questions about your child and your home.
Readiness signs
Signs to look for, not a checklist to pass.
- Names familiar objects confidently
- Enjoys guessing games
- Can keep hands inside a bag without peeking
What to gather
A drawstring cloth bag and five or six familiar objects from around the house
How to present it
Show it slowly and in silence. Your hands are the lesson.
- 1Show each object and name it, then place them in the bag together.
- 2Reach in, feel one object, and say what it is before pulling it out.
- 3Take it out and check.
- 4Offer the bag to your child.
What to say — and what to avoid
Say
- I feel something round and cold.
- What do you think it is?
Avoid
- No peeking!
- That was easy
Control of error
Pulling the object out immediately confirms or corrects the guess.
What to observe
Take these into the next cycle rather than judging the session.
- Does your child describe before naming?
- Do they want harder objects?
- Do they ask to fill the bag themselves?
Simplify or extend
If it's too hard
Use three very different objects — a spoon, a ball, a pinecone.
Once it's mastered
Use pairs of similar objects, or matching pairs found by touch alone.
